CABLE ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed May 4, 1906. Serial No. 315.160%.

To all whom it may concern.-

Be it known that I, FREEMAN R. WILLsoN, Jr., a citizen of the UnitedStates, residing at Worthington, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in CableAttachments, of which the following is a specification v 1 referencebeing had therein to the accompanying drawing.

This invention relates to improvements in cable at- .0 tachments for carhaul systems, it pertaining particularly to the manner of securing; tothe cable the trucks or carriages which carry the spurs or arms whichare adapted to engage with a cooperating element on the car to becontrolled.

One of the objects of the invention is to provide a simple, durable andlight attachment or clamp which may be quickly secured to or detachedfrom the cable.

Other objects of the invention will be set forth in the description of adevice embodying it, which I have herein presented for the purpose ofillustration.

Figure 1 is a side elevation of a device embodying my improvements; Fig.2 is a front end elevation of the same; Fig. 3 is a plan view; Fig. 4 isa section on the line 4-4 Fig. 1; Fig. 5 shows a detail.

In the drawings 1 indicates as an entirety a cable clamp or attachment.It is preferably formed in two parts, an upper one 2 and a lower one 3arranged parallel with each other along the cable and separable from*each other on lines longitudinal of the cable and of the clamp itself.These parts of the clamp or attachment are preferably detachably securedtogether by bolts 4 having at their upper ends nuts 4.

Each cable-attachment preferably carries near either end atransversely-arranged axle 5 on which is mounted at either side of theclamp or attachment anti-friction wheels or rollers 6 which are adaptedto support the clamp or attachment as it is traveling along thedifferent circuits or run of the car haul system.

The lower part 3 of the clamp or attachment is centrally andlongitudinally grooved as indicated at 3 to receive the cable which isindicated by 7. The upper section or part of the clamp or attachment isalso cen trally and longitudinally grooved as indicated at 2 to Ireceive the cable and at points immediately above the axles 5 at eitherend of the attachment the groove 2 is increased in depth as indicated at2 in order to permit the forming of a kink or bend in the cable at thesepoints so as to insure the secure fastening of the attachments or clampsto the cable and prevent relative longitudinal movement of the saidparts.

The bearings for the axles 5 are formed in both the upper and the lowerportion of the clamp in such way that when the said parts of the clampare separated the axles can be bodily lifted laterally from the lowerportion 3 of the attachment. Each of these axles near its center isslightly curved or bent downwardly as indicated at 5 in such manner thatwhen the axle is in position the upper surface of this curved portionwill engage with the under surface of the cable '7 and force the cableup into the cooperating deeply recessed part 2 of the upper portion ofthe clamp the transverse grooves through the clamp conforming with thecurves of the axles.

, S is a spur or arm pivotally mounted at 8 between i upwardly andforwardly extending arms 2 2 carried by the upper section of the clampor attachment. This t tilting spur 8 has a forwardly and upwardlyextending i arm S and a rearwardly extending arm 8* of greater 5 lengththan the arm 8, which tends normally to hold i the said arm 8 in itsupright position. The arm 8 is l adapted to engage with the uppersurface of the part 2 l of the clamp in order to limit the rotation ofthe spur 8 l in an anti-clockwise direction beyond a predetermined 1point. 2 is an upwardly extending stop arranged in l the path of travelof the arm 8 and adapted to limit the downward travel of the said arm.This tilting spur opi erates in the well-known manner to permit acooperat- 'ing element or attachment on a car to ride over it in onedirection, while engaging with it so as to advance the car when thepressure between it and the cooperating l element on the car is appliedin the opposite direction.

It will be understood that, if desired, the upward exi tending spur orarm may be rigid with or formed inte- 1 gral with the upper portion ofthe clamp.

I am aware of the fact that it has been heretofore prol posed to form aclamp somewhat similar to the clamp herein described, also formed in twoparts separable on a longitudinal line, having cable-receiving groovessomewhat similar to the ones I have shown and employing wheel-carryingaxles arranged to kink or bend the cable within the clamp, such, forexample, as shown in Patent #722,951, dated March 17th, 1903, to o. W.Damron. In the earlier construction, however, the axles were straightthroughout their length and were inserted by pressing themlongitudinally through bearings arranged entirely within the lowerportion of the l clamp. These axles could neither be inserted norwithdrawn laterally, when the parts of the clamp or attachment wereseparated, but had to be withdrawn longitudinally. Applicantsconstruction simplifies the assembling and dismantling of the cabletrucks or attachments, and by bending the axles at their centers, 1 asshown, applicant has succeeded in decreasing the vertical thickness ofthe clamp and consequently lessening its weight.

What 1 claim is: V

l. A cable attachment comprising two parts separable on longitudinallines, and each provided with a longitudinal groove arranged to receivea portion of the cable and with a transversegroove arranged to receive aportion of an axle, an axle fitted into said transverse grooves, androllers on the axle.

2. A cable attachment comprising two parts separable on longitudinallines and each having a longitudinal groove and a transverse groove, thelongitudinal grooves cooperating to receive the cable and the transversegrooves cooperating to receive an axle, an axle fitted into saidtransverse grooves, and rollers on the said axle.

3. A cable attachment comprising two parts separable on longitudinallines and having transverse grooves ar ranged to register with eachother and to receive an axle and longitudinal grooves adapted to receivethe cable, the longitudinal groove in the upper part of the clamp beingdeeper immediately above the point at which the axle is inserted thanelsewhere throughout its length, an axle fitted into said transversegrooves and adapted to force the cable into the deeper portion of thesaid upper longitudinal groove, and rollers on said axle.

4. A cable attachment formed in two parts, an upper and a lower one,separable on longitudinal lines and hav ing transverse grooves arrangedto register with each other and to receive an axle and correlatedlongitudinal grooves arranged to receive the cable, the longitudinalgroove'in the'upper part of the clamp being deeper iminediately abovethe point at which the said axle is inserted than elsewhere throughoutits length, an axle fitted into said transverse grooves and having itscentral por tion bent downwardly and arranged to engage the cable and topress it into the said deeper portion of the longitudinal groove in theupper part of the clamp, and rollers on said axle.

5, A cable attachment formed in two parts, an upper l I l l and a lowerone, separable on longitudinal lines and hav- 1 ingtransversely-arranged curved grooves adapted to regis ter with eachother and to receive an axle and cooperating longitudinaIly-arrangedgrooves adapted to receive the cable, the longitudinal groove in theupper part of the clamp being deeper immediately above the point atwhich the said 4 axle is inserted than elsewhere throughout its length,an axle fitted into said transverse grooves and having its centralportion bent downwardly and adapted to press the cable upwardly into thesaid deeper portion ofthe longitudinal groove in the upper part of theclamp, and rollers 4 on the axle.

6. In a conveyer carriage, the combination of the body part, a bentaxle, the body part having a depressed seat receiving the bent portionof the axle, means for clamping the axle in the said seat, and Wheels onthe axle.

7. In a conveyor carriage, the combination of a body part, an axle roundin cross section and bent intermediate its ends, the body part having adepressed seat receiving the bent portion of the axle, means forclamping the axle in the said seat and wheels on the axle.

8. In a conveyer carriage, the combination of a body comprising twoparts separable on longitudinal lines, a bent axle, one of the bodyparts having a depressed seat receiving the bent portion of the axle,-means for clamping the two body parts together and thereby in position,and wheels on the axle.

In testimony whereof I afiix my signature, in presence of two witnesses.
